P191 MINIMALLY-INVASIVE ESOPHAGECTOMY IN TREATMENT FOR ESOPHAGEAL DISEASES

Abstract Aim to study the benefits of the mini-invasive approach. Background & Methods 115 esophagectomies were performed for the period from 2015 to 2018. Gastric conduit in 84 patients, colon - 2 and small intestine - 29. The study included 65 patients after I.Lewis, McKeown or transhiatal esophagectomy, who was performed esophageal replacement with gastric conduit. The first group consisted of 44 patients after open esophagectomy; second group - 21 patients after MIE (minimally invasive esophagectomy): included 8 patients - thoraco-laparoscopic McKeown surgery, 1 patient - laparoscopic transhiatal esophagectomy with anastomosis on the neck, 9 patients – hybrid minimally invasive I.Lewis surgery (laparoscopy+thoracotomy), and 3 patients – minimally invasive thoraco-laparoscopic I.Lewis surgery. The average age of patients was 53 years (13-64). 55 patients (84.6%) with esophageal cancer and 10 patients (15.4%) with benign strictures of the esophagus. There were anastomosis on the neck in 28 patients (43%) and intrathoracic anastomosis in 37 patients (57%). Results In the first group the average operative time was 286 minutes (240-370 min.), the average volume of blood loss was 345 ml (100-600 ml), the length of in-hospital stay was 15 days (9-29), complications: anastomosis leakage - 1 patient on the 5th postoperative day - EndoVAC system was used with a defect closure after 18 days; 1 patient - adhesive intestinal obstruction (relaparotomy, separation of adhesions). In the second group the average operative time was 400 min (370-480 min.), blood loss - 100 ml (50-200 ml), the length of in-hospital stay - 10 days (8-16), complications in 1 patient - acute strangulation with intestinal obstruction. There was no mortality in both groups. Conclusions The application of MIE helps to reduce the severity of postoperative pain, the length of in-hospital stay and intraoperative blood loss. This procedure should be performed in specialized hospitals with experience in miniinvasive surgery and esophageal surgery.
